With the last official update to the pre-alpha slated to come out tomorrow, and a new moon being added with T2 before they crank out 1.0, I wanted to share this, not knowing if any of the info would change. I also have not seen anyone look at this yet, so if someone has, I'd love to double check my numbers against theirs. TL;DR, I found the orbital periods (Sidereal Periods) of each planet currently in the game, their resulting Synodic Periods with each other planet, and discovered System Era likes Lucky Numbers (using the Sieve of Josephus Flavius), within error.
This post does not go into great detail about what sidereal or synodic periods are, or lucky numbers. The methods used and results are given. Personality Type-D people looking for pragmatic information can use the table shown here. This table outlines when a given planet will align synodicly with any other planet in opposition, same side of the star. This excludes Barren, which was only calculated with Terran. Yes, the table below shows you'd have to wait longer than 25 minutes to launch from Terran to Tundra from the same point. Given the planets are slightly closer that the edge of Terran's launch-range, the actual time needed to wait before being able to reach Tundra is slightly less. This is why experienced players recommend planet-hopping if you have a Hydra-zine Thruster capable shuttle.
Terran is represented as H, for Home-Planet. Tundra to Radiated is highlighted in Red, as it is impossible to travel directly between the two bodies given the distance.
Before divulging my methods, the answer to the WHY? question is that I have always been fascinated with how we can tell for certain how planets move, and wanted to try for it myself. I was also inspired by the loading screen, given the very nice round number they chose. It is clear the loading screen was designed very intentionally with this concept in mind.
Loading Screen.
If you watch the loading screen long enough, you see that the each planet from the star completes five, three, and one orbital cycle from the first planet outward respectfully, before realigning. Those figures happen to have a very short total synodic period.
Alignment 1, T=0 is six seconds into the recording.
Alignment 2, Dropping frame-rate caused capture issues.
Also note, that satellites, like Barren, have a synodic period based on the planet they orbit. Additionally the next image illustrates that just because two bodies align synodically, it does not have to be from the point they were last aligned.
Synodically aligned, not at origin.
So to find the in-game sidereal periods of each planet, I began with Radiated. It is obvious it has the fastest orbit around the star, thus I could record significantly less. One difficulty in using Radiated is that most of the error in time stepping comes from not having a camera-lock feature in launch mode (I don't want one either) and another is the increasing distance to other planets increases reliance on video resolution. To begin, I calculated the sidereal period of Radiated. Then I timed the synodic period with every other planet. Using the equation below, you can find the missing sidereal period of the other planet in question. Then I verified my calculations by observing the sidereal period for both Terran and Arid. I quit after that because I was disheartened about likely losing my saves with tomorrow's update. Screenshots with time stamps showing what was used in the image are given below.
Equation Used. Note, absolute value in the denominator.
The results shown in the table here have striking similarity, within rounding, to Lucky Numbers found using the sieve above, after the 7th-number filter. Coupled with the deliberate choice in the loading screen, I hypothesize this is very intentional. This also adds huge favor of System Era in my book!
Results. Note Barren's Synodic Period is in relation to Terran (H).
Finding the Least Common Multiple for all sidereal periods of the planets, excluding Barren, the total synodic period ranges anywhere from 61 to over 1,000 years. These numbers vary largely when even one sidereal period is altered by a fraction of a percent. As such, it is currently inconclusive just how long one will have to wait to get the "perfect" screenshot with all planets in superior opposition to Radiated with respect to the star. It is also inconclusive what my current error is as the official sidereal periods are not posted anywhere. Seeing as I was able to use a game to teach myself basic concepts in astrophysics, I support leaving these numbers unpublished as well. If anyone has done this and would like to compare, let me know!
For more math fun, because the orbits are periodical, they can be represented by a sine wave. Therefore each planet has a frequency. Because there are multiple frequencies, the resulting sinusoidal wave will change shape, exactly like adding musical frequencies that can develop beats. By adding each planets wave, you can find the overall solar system's wave function in regards to the orbit.
Yes, I know I have way too much time on my hands. Sorry for the long post, thanks for the read!

I came across an obviously fake application claiming to be Astroneer on the Google Play store.
Title: Astroneer: New Adventure
Developer: EVGENUY
Contact: evgen.chuyashenko@gmail.com
All the reviews say the app doesn't open, but has a "start" button. Very likely a virus as well as containing ads to make them money.
I reported all of their apps to Google, but they don't have a label for fake app or virus. I hope someone at System Era sees this and can try to get it removed.

Why is this game still a complete fail after months? The team has had literal months to work on things and it feels like the game has regressed.
Rover Handling
I still cannot drive a rover without having it fly into the atmosphere and the time that I do get with the rover on the troposphere is spent trying to flip the rover over because its handling was implemented by a four year old.
Crafting & Research
Why can I no longer craft a tank or small battery on my backpack? Why was there no on screen notification saying that the way small batteries and tanks can be crafted has been changed? Does System Era know anything about game design? I can understand a lack of tutorials for pre alpha games but the communication of the games mechanics to the player is nonexistent. There at a minimum should be a visual menu that accompanies the tiers of research and what has and has not been researched in each tier. I have researched countless parts/rocks/plants and still cannot build a small tank or small battery. There was even a time on my current save (7/10/2017) that I could build small batteries and the ability has since been removed. The research system is disgustingly broken. The fact that I can get anything from a single compound to the research behind a habitat from research components is just flat out terrible game design. Spending half an hour excavating and bringing back a research part only for it to yield compound is nothing short of insulting. How come when I scroll through the vehicle bay options sometimes a large rover will show up even though I have not researched it? What can I do to actually get the large rover researched so it will show up in the vehicle bay every time and not just when the game bugs in my favor? Still cannot build a large rover/truck after hours of researching.
Co-op
How come when I join another host I can only see structures built on Terran? Structures built on literally every other terrestrial object (moons and other planets) can only be seen by the host. The cooperative tag should be removed from this game on the steam store because co-op in this game is disgraceful and simply cannot work if what is being built is invisible to me…how lame
Review
Maybe this game is a huge mess of physics and making changes is harder than I could ever imagine so not fixing things like the rover handling or seems in the map can be understood but structure visibility is another story. I do not know what could be so complex about making all structures visible for all players across the whole solar system. Is this something as simple as changing a visibility Boolean? What complex unsolvable algorithms could be behind something as simple as making a skin/texture visible to all the players?
I know people are working on the game and it looks like System Era is a growing company but this game feels unchanged from its December release? Are the people working on the game too busy to finish it?
What a pathetic display for game development industry as a hole. I apologize for my terrible attitude but my friends and I feel like we wasted our money on a half-baked game that will not see completion within any relevant time frame.

Ok so I don't know if this is just me but in the past five saves I've made, I start out with a decent amount of compound, but after a while I can't find any compound for miles and honestly it's a huge problem. In games like Minecraft (sorry to make this comparison) one of the most essential materials for crafting is wood, which is made abundant near spawn, and really just surrounds the whole world. I understand the concept of scavenging and actually having to look for certain materials but i now have five save files that i can no longer play because I have no compound. Also, i never waste tethers; i place them as far apart as possible. Another thing: what's up with all the resin? If it's something wrong with my copy of the game, please tell me if there is a solution to this. Also, please tell me if you agree. I really can't play the game with such a lack of compound.
